To close this one out. It was the throttle position sensor. It did not leave a hard fault in the memory. Dealer essentially took a "shot in the dark" and replaced the sensor and that solved the problem. thanks everyone!
Your post above is incorrect and you need to check your sources for the flawed information you posted... The transmission in ALL Cayenne's thru model year 2009 is the Aisin 09D TR60SN. ZF does not make ANY replacement parts for any transmissions other than ZF. Aisin is the sole OEM supplier for replacement valve bodies for the 09D TR60SN. The valve bodies that the dealer is currently selling is the exact same design. It has the same casting and solenoid defects as the the failing valve bodies do. -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- ZF rebuilds the valve body here (Germany...not USA). Wishing not to revisit the sound of a sledge hammer under the car when down shifting I made sure to ask where the replacement came from. ZF offers a range of services including rebuilding and supplying replacement parts follow the link and see for yourself. "These are comprehensive selections from ZF-owned brands like SACHS and ZF Parts, as well as non-ZF brands." http://www.zf.com/media/media/document/corporate_2/products_3/services_2/remanufacturing_1/zf_reman_brochure_EN.pdf The package I saw had a return address here: ZF Friedrichshafen AG Powertrain TechnologyPostfach 65 04 6466143 Saarbrücken
As of right now it is the Throttle Positioining Sensor....an 80 euro part. :thumbup: It was tested twice while I was there...and apparently it was within tolerance. But, the technician appeared to almost argue (in a polite manner) with the senior mechanic that this was indeed the fault. I am also having the right side headlight mounting plate replaced while it is there so the dealer can properly aim the headlights.
Well not having an OBD code reader makes it a little hard (durametric not compatible with Mac). I would have thought the CEL should have came on. thanks~
Hello all, I have been lurking around here for almost 2 years. I have a 2006 Cayenne S with automatic transmission with about 70,000 miles. This morning I went to drive it to the car wash. When I went to accelerate onto the autobahn the engine acted as if it were in limp mode. There was no power under load above 3,500 RPM. In neutral the engine will not rev past 4200 RPM. Here is what it is not doing or has been replaced - It starts and idles fine. - plugs and coils replaced last year less than 10 thousand miles ago. - I do not have a check engine light on. I am thinking: 1. MAF sensors (looks like a special tool required for replacement). 2. Throttle position sensor 3. Fuel Filters 4. Fuel Pumps 5. Or another sensor related to fuel pressure or fuel regulation/delivery system. Does anyone have any trouble shooting tips or advice before I give up and take it to the dealer?
"Currently new valve bodies acquired from the Porsche dealer will still be the same flawed design as the originals. The only way to permanently fix the issue is with an upgraded aftermarket valve body." The Porsche replacement is NOT sourced from Asin. It is a brand new part made by ZF in Germany so I assume all of the those issues are solved. There was no core return, I could have taken the old part home! I asked this prior to replacement because I did not want to visit this issue again in another 40 thousand miles. I had my valve body replaced at my dealer in Reutlingen Germany. At the time she had about 43K miles and had been exhibiting symptomatic whacks or clunks for a few months. The only way around the issue was to lift off throttle & coast, manually down shift into 4th. Once I felt it slip into gear then I gave it the beans. I am happy to report it shifts wonderfully now.
It should "pop" into place. If you look at the rotating levar (bar) on the housing tray or platform it should rotate away towards the back of the car.
The exact same thing happend to me yesterday afternoon. I was simply trying to replace the turn signal bulb when the plug felt "funny" coming out. The plastic tabs that hold the round carrier (with metal leads/contacts) to the housing broke allowing the round carrier to move fore and aft inside the housing. After trying fruitlessly to secure the carrier in place I took the car to my dealer and to my delight they were able to secure the round carrier in place well enough to seat the the bulb. So I guess I am eventually out the 700 bucks or so for a used head light assembly. But for now I am good. Another potential option is to build a pigtail off from the plug and splice into the brown and black leads within the housing. The bulb should stay in place with just the rubber gasket in place. Essentially you would build in about 6 inches of pigtails allowing enough slack to replace the bulb in the future. There is plenty of extra dead space in the main light assembly behind the daytime running lights/flash to pass lights. I think this is the part number for the broken ring 95563123300. I see no real way to replace it with out cracking into the light assembly.
sounds like it is time to replace the transmission valve body. You may get lucky and flush the transmission, but due to what is clearly a manufacturing defect with the shifter solenoids it will need to be replaced. A common malady with Cayennes & Tuaregs of your vintage.
I called sunset and their prices were no different than the dealer here near Stuttgart DE. go figure!
second the motion on the solenoid on the transmission. In the vast majority of cases it is a complete valve body replacement.
Concur even the small amount of fluid from slave cylinder leak if it were to somehow find its way in to the throwout bearing would not harm it (the bearing is sealed). The clutch disk may slip until the fluid burns off.
Just picked mine (06 Cayenne S US Spec) from the dealer in Reutlingen Germany. Total Damage was 3100 USD (2400 Euro). I was told the replacement valve body was a new unit from ZF & there was no core charge. Parts were cheaper here including a 19% VAT than in the US...go figure? You might be able to save a few bucks going to a reputable mechanic/transmission shop. The procedure is pretty straight forward (drain, drop pan, unbolt valve body, bolt new body, check torq, replace filter & pan, refil, test, chk for leaks). If I had more time I may have attempted repair myself. Problem first discovered (noticed) in August of 2011 at about 51 thousand miles. It currently has about 59 thousand. Your symptoms describe to a T my problem. Flared 4-5 upshifts & large physical CLUNKS 5-4 down shift but, only under moderate to heavy load with down shift. This is a VERY common fault also with Touregs of the same year (04-06) no surprise it is the exact same transmission. HINT maybe a VW source part and labor may be cheaper? Vehicle did not throw a code. Dealer did not believe me until I drove it for him and replicated the CLUNK right no que.. Both TCU cables were replaced. There was a slight coating of transmission oil on both from a leaky seal/fitment. In the grand scheme of things they did not add much to the total cost. The best solution for automatic transmission problems is buying a manual in the first place. But, it is my wife's car and hauls 5 pax with gear on the autobahn at 90-100 mph with out so much as breaking a sweat. Probably the best grand touring car I have ever driven. Plan to keep it for several years and bring it back home from Germany. Good Luck
